Clean your KitchenAid ice maker every three to six months, or more often if you have hard water

A KitchenAid ice maker needs regular cleaning to prevent mineral buildup, mold, and off-tasting ice. The exact steps depend on whether your model is built into a refrigerator or is a standalone countertop unit, but the basic process is the same: drain the water, wipe the interior, run a cleaning cycle if available, and flush the system.

Most buildup happens inside the water lines and the ice-making mechanism, not just the visible parts. If you ignore cleaning for months, you may notice ice that smells stale, tastes metallic, or looks cloudy — all signs that mineral deposits or bacteria are present. The good news is that cleaning takes less than an hour and requires only household items you likely have already.

Key Takeaways

  • Turn off the ice maker and empty the bin before you start, then locate the drain plug or drain line at the bottom of the unit.
  • Use white vinegar to dissolve mineral deposits inside the water lines and ice-making chamber, letting it sit for 15 to 30 minutes before rinsing.
  • Wipe down the ice bin, chute, and visible interior surfaces with a damp cloth, then dry everything thoroughly to prevent mold.
  • Run fresh water through the system for several minutes after cleaning to flush out vinegar residue before making ice again.
  • If your KitchenAid has a cleaning mode or self-cleaning cycle, consult your manual for the exact button sequence and timing.

What you need before you start

Gather white vinegar, a soft cloth or sponge, a small brush (an old toothbrush works), a bucket or large bowl, and your ice maker's manual. You may also need a wrench or pliers if the water line connection is tight, though most KitchenAid models use a push-fit connector that requires no tools.

Check your manual for the location of the drain plug and the water inlet. Some countertop models have a small drain valve at the bottom front; refrigerator-mounted units may drain into a pan underneath or into a floor drain. Knowing this before you start prevents water from spilling onto your floor or inside your refrigerator.

Drain the water and empty the ice bin

Turn off the ice maker using the power switch or the control panel. If your model has an on/off switch on the water line itself, turn that off too. Open the ice bin and remove all ice — throw it away or use it up, since you will not want to use ice made before cleaning.

Locate the drain plug or drain valve. On countertop models, this is usually a small plastic knob or cap at the bottom front. On refrigerator units, it may be a pull-out plug or a valve you turn counterclockwise. Place a bucket underneath and open the drain slowly — water will flow out. Let it drain completely, which usually takes two to five minutes depending on how much water is in the system.

Clean the interior surfaces and ice chute

Once the water has drained, use a damp cloth to wipe the inside of the ice bin, the chute where ice falls, and any visible surfaces. Pay attention to corners and crevices where mold or slime can hide. If you see dark spots or buildup, use a soft brush or old toothbrush dipped in white vinegar to scrub gently.

Do not use abrasive scrubbers or harsh chemicals — they can scratch the plastic or leave residue that flavors your ice. Vinegar is safe, effective, and leaves no chemical taste. After scrubbing, wipe everything down with a clean damp cloth to remove vinegar smell, then dry with a towel.

Run vinegar through the water lines

This step removes mineral deposits from inside the machine where you cannot see. Fill a small bowl or cup with white vinegar. Locate the water inlet — this is where the water line connects to the ice maker. On some models you can pour vinegar directly into a fill port; on others you may need to disconnect the water line temporarily and pour vinegar into the inlet opening.

Let the vinegar sit in the lines for 15 to 30 minutes. This gives it time to dissolve calcium, lime, and other mineral buildup. If your KitchenAid manual mentions a cleaning cycle or descaling mode, follow those instructions instead — some models have a button sequence that automates this step and uses the right amount of vinegar for your specific unit.

Flush the system with fresh water

After the vinegar has sat, reconnect the water line if you disconnected it, or close any fill port you opened. Turn the water back on and run the ice maker through a full cycle without the ice bin in place, letting water and any remaining vinegar drain into a bucket. Repeat this cycle two or three more times until the water runs clear and you cannot smell vinegar.

This flushing step is important — vinegar left in the lines will flavor your ice and make it taste sour. Do not skip it. Once the water runs clear and smells normal, replace the ice bin, turn the ice maker back on, and let it run for one full cycle before using the ice.

How often to clean and what to do about hard water

In areas with soft water, cleaning every six months is usually enough. If you have hard water — you will notice white or chalky buildup on faucets and fixtures — clean your ice maker every three months instead. Hard water contains more minerals that accumulate faster inside the machine.

If you live in a very hard water area, consider installing a water filter on the line that feeds your ice maker. Many hardware stores sell inline filters designed for refrigerators and ice makers. These reduce mineral buildup and extend the time between cleanings. Check your manual to see if your KitchenAid model has a built-in filter that needs replacing — some do, and a clogged filter can slow ice production.

Frequently Asked Questions

Can I use a commercial ice maker cleaner instead of vinegar?

Yes, commercial cleaners made for ice machines work well and sometimes work faster than vinegar. Follow the product instructions exactly — most require you to dilute the cleaner, run it through the system, and flush with water several times. Vinegar is cheaper and works just as well for routine cleaning, but commercial cleaners are useful if you have heavy mineral buildup or mold.

My ice maker is making cloudy ice — is it dirty?

Cloudy ice usually means minerals in the water, not dirt. Cleaning the ice maker will help, but the real fix is a water filter. If your KitchenAid has a replaceable filter cartridge, change it. If not, an inline filter on the water supply line will reduce cloudiness and mineral buildup inside the machine.

What if water leaks when I open the drain?

Place a bucket or towel under the drain before opening it — water will come out. If water leaks from the connection itself after you close the drain, the seal may be worn. Check that the drain plug is tight, or consult your manual for the correct tightness. If it still leaks, the seal may need replacing, which is a job for a repair technician.

Do I need to clean a new ice maker before using it?

Yes. Run water through the system for several minutes and discard the first batch of ice. This removes any dust or manufacturing residue from inside the machine. After that, follow the regular cleaning schedule based on your water hardness.

Can I clean the ice maker while it is still plugged in?

No. Always turn off the power and unplug the unit before opening it or working on the water lines. This prevents electric shock and accidental set up of the ice-making cycle while you are working inside.
